UNITED STATES PATEN T OFFTOE.

JOHN C. GOAR, OF MONTEREY, CALIFORNIA.

BELT-SHIPPER.

Specification of Letters Patent No. 29,587, dated August 14, 1860.

To all whom it may concern:

Be it known that I, JOHN O. GOAR, of Monterey, in the county of Monterey and State of California, have invented a new and useful Improvement in Belt-Shippers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- 4 Figure l, is a front view of a belt shipper with my improvement. Fig. 2, is a transverse vertical section of the saine. Fig. 3, isa horizontal section of the same.

Similar letters of reference indicate corresponding parts in the several figures.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, represents a cast iron plate or any fixed piece of metal or wood tO which are attached the fixed horizontal guides n, a, a', within or between which works the shipper slide B, in which is the slot Z), which receives the belt D.

E, E, are the two stops consisting of elbow shaped levers working on fulcrum pins c, 0, secured in the slide B, and each having a square tooth (l, to enter one of two square notches e, e, in the low-er guides a', a, the said notches and stops being so arranged that when the slide is in position to keep the belt upon the pulley F, the tooth of the stop E, enters the notch e, and when the slide is in position tO keep the belt upon the pulley F', the tooth of the stop E, enters the notch e, in either case locking the slide and securing the belt upon the pulley F, or F', as the case may be.

Or, is a double spring secured to the slide B, and Operating upon both stops to force their teeth downward so that they will drop automatically into their' respective notches as they are caused to arrive over them by the movement of the slide and thus lock the slide.

g, g', are slot pins secured in the slide B, to arrest the spring stops E, E', when the latter' have been drawn out of the notches e, e.

H, H, are two cords or chains attached .one to each of the stops E, E, and each passing over one of two pulleys lI, I, working in frames J, J attached to the plate or stationary piece A, and hanging down therefrom tO-a suitable position to be laid hold of by the person whose duty it is to ship the belt.

In the drawing the shipper slide is represented locked by the stop E, in a position to keep the belt D, upon the right hand pulley F When it is desired to ship the belt on to the left hand pulley F, the attendant pulls the cord Or chain H, and by that means irst draws the spring stop E, out of the notch e and into Contact with the stationary stop g, and then draws the slide to the left, and draws the belt over to the pulley F, and when the belt arrives there the tooth of the stop E, arrives at the notch e, and by dropping thereinto, locks the slide. In like manner when the slide is in the latter position and the cord or chain H, is pulled, it firstdraws the tooth Of the stop E, out of the notch e, and then draws the slide B, to the right and ships the belt on to the pulley D, and the stopv E, drops into the notch e, and locks the slide.

That I claim as my invention and desire to secure by Letters Patent, is,-

The arrangement of the pivoted locks or stops E, E, and their spring G, upon the face of the belt shipper or slide B, in the manner herein shown and described, so that pressure upon either of the cords H, I-I, will first unlock the corresponding stop and then move the slide, all as set forth.
